Gundam is the titular mobile suit of Mobile Suit Gundam. The Gundam was incredibly advanced for its time. Built from lightweight Luna Titanium Alloy, its frame was both lighter than that of Zeon's mass-produced mobile suits and much sturdier, able to shrug off a Zaku II's machine gun fire with little to no damage. Its offensize power was above and beyond that of the Zeon Zakus.
